TROUBLESHOOTING GUIDE:
ISSUE ACTION
FURNACE – NO HEAT Check fire. Refuel as needed. Press the “ START ” button (C) on
Electronic Control System.
Check Circulator Pump. Visually check to see if pump is functioning.
If the circulator pump is not, then disconnect from power and
inspect. If circulator pump has failed contact your Northern Stoker
Dealer.
Check control panel for RED indicator lights ON (B) or (F).
Scenario: if the temperature reads 122˚ F (50˚C) and you are loading
cold wood into the firebox, the temperature can decrease by 3˚F. This
will trip the low temperature alarm (<120˚F) and shut the fan off. The
operator must wait and press the “
START ” button (C) to restart.
Check that combustion chamber blower fan toggle switch is ON .
Press the “ START ” button (C) on Electronic Control System.
Check that the combustion chamber blower fan and damper are
functioning.
Check chimney for blockage. If blocked, remove debris.
If the Northern Stoker is attached to existing primary heat source
(Example: Fan Forced Furnace), make sure that existing primary heat
source is operating correctly.
If the temperature reading is inaccurate, check that the temperature
probe has a loose connection, come out of the drywell or has failed.
Contact your Northern Stoker dealer for service and repair.
FURNACE – BOIL OVER CONDITION
Note: If the furnace has boiled over, check the
water level and fill if needed. Low water will
introduce air into the water system and can damage
the circulator pump.
Check the combustion chamber loading door that it is not open.
Close if it is. Check that the air damper is closing properly between
fan and furnace.
Check door gaskets and seals, they need to be tight fitting and not
allow air into combustion chamber. If gaskets and seals are worn or
hard, contact your Northern Stoker Dealer to replace them.
Check ambient temperature. If outside temperature is to warm, lower
your set temperature. Make sure the circulator pumps are on. By
circulating and mixing the return water, it will aid in balancing the
temperature of the furnace.
